Analyze and fix the following issue in the Linux kernel code: dm integrity: reduce vmalloc space footprint on 32-bit architectures
Problem Details: It was reported that dm-integrity runs out of vmalloc space on 32-bit architectures. On x86, there is only 128MiB vmalloc space and dm-integrity consumes it quickly because it has a 64MiB journal and 8MiB recalculate buffer. Fix this by reducing the size of the journal to 4MiB and the size of the reca...
